Scientists at the Joint Quantum Institute (JQI) have been steadily improving the performance of ion trap systems, a leading platform for future quantum computers. Now, a team of researchers led by JQI Fellows Norbert Linke and Christopher Monroe has performed a key experiment on five ion-based quantum bits, or qubits. They used laser pulses to simultaneously create quantum connections between... Continue Reading

Everything radiates. Whether it's a car door, a pair of shoes or the cover of a book, anything hotter than absolute zero (i.e., pretty much everything) is constantly shedding radiation in the form of photons, the quantum particles of light.A twin process—absorption—is usually also present. As photons carry away energy, passers-by from the environment can be absorbed to replenish it. When... Continue Reading

The University of Maryland will host the 2nd North American Conference on Trapped Ions (NACTI) from July 22-26. This year’s conference comes two years after the inaugural meeting, which was held on the Boulder, Colorado campus of the National Institute of Standards and Technology (NIST).More than 230 students and researchers from around the globe, all...

Alexey Gorshkov, a JQI Fellow and a Fellow of the Joint Center for Quantum Information and Computer Science, has received a Presidential Early Career Award for Scientists and Engineers (PECASE). The honor, which is the most prestigious offered by the United States Government to young researchers, ... Continue Reading

Researchers at the Joint Quantum Institute (JQI) have created the first silicon chip that can reliably constrain light to its four corners. The effect, which arises from interfering optical pathways, isn't altered by small defects during fabrication and could eventually enable the creation of robust sources of quantum light.That robustness is due to topological physics, which describes the...
